Abstract

Divulgation d'un système pour clarifier des résidus fins dans une suspension d'eau dans des bassins de résidus de sables bitumineux. Ce système est basé sur l'électrophorèse pour collecter les résidus fins sur des électrodes respectives lors de l'application d'un premier potentiel électrique aux électrodes. Les résidus fins ainsi collectés peuvent être déposés vers une zone de collecte sous les électrodes lors de l'application d'un deuxième potentiel électrique de polarité opposée. On continue d'appliquer les premier et deuxième potentiels alternativement aux électrodes jusqu'à ce que le fluide soit substantiellement exempt de ses résidus fins en suspension.
